Problem 29CQ
In view of the small currents that cause shock hazards and the larger currents that circuit breakers and fuses interrupt, how do they play a role in preventing shock hazards?
ANSWER:
Solution 29CQ
As whenever a current larger to that of a fixed threshold level passes through the circuit, the circuit breakers or fuses interrupt the flow of current, the fuses consists of a metallic connection having low melting point, which connects two ends of the circuit, whenever a large current tries to pass from it, due to overheating, the metallic connection blows out and hence interrupt short-circuit.
